I might be wrong here, but I think both were supplied by the same place, or one supplied the other. Something like that. As for MGN they said they changed factories or warhouses and the batches they released after their first successful ones were very gritty. They also had customer service issues. Then they just kinda vanished.
Also dident ATW get in trouble / get heat for poor sanitation conditions or something? I remember a thread about it on another site getting real.
